Arcane Disk

A sharp disk of arcane energy, It resembles a small puck when not in use and is able to expand with a projection of solidified arcane energy in the shape of a disk (or something else depending on flavor) small enough to fit in your hand. The disks remain expanded for 10 minutes at a time before the energy runs out. It emits bright light at a distance of 15 feet and dim light for another 15 feet and does not hurt you when held. Upon a hit the disk will deal 1d8 Slashing Damage and then will dispel instantly and vanish. As you grow in power you will be able to utilize more arcane disks at a time, a second disk at level 5, a third at lvl 9, a fourth at lvl 13, and finally a fifth at lvl 20.
